METALLIC SHINGLE.

SPECIFICATION forming part of Letters Patent No, 294,256, dated February 26, 1884.

Application filed November 23, 1883. (No model.) l

.T 0 @ZZ when?, it may concern.-

Be it known that we, LEVI H. MoN'rRoss and JoHNC. WEST, of Simcoe, in the county of Norfolk, in the Province of Ontario, have invented new and useful Improvement-s in Metallic Shingles, of which the following is a specification.

This invention relates to an improvement in that class` of shingles which are constructed of sheet metal andrprovided with raised ribs, whereby the shingles are stiifened and interlocked with each other.

The object of this invention is to produce a shingle which is stiffer than those heretofore used without any increase in the weight of the metal employed, and which is more securely interlocked with the adjoining shingles, and by which the joints are better guarded against snow or rain than heretofore.

Our invention consists, to these ends, of the improvements in the construction of the shingle, which will be hereinafter fully set forth., and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a top view of our improved shingle. Fig. 2 represents a view on a reduced scale of a number of our improved shingles laid along the eaves of the roof. Fig. 3 is a crosssection in line w x, Fig. 2, on an enlarged scale.

Like letters of reference indicate like parts in the several iigures.

The'body A of the shingle is square, or nearly so, and arranged with two corners in the vertical central line of the shingle. 'The lower corner of the shingle is provided with alip, a, which serves to secure the lower corner to the adjoining lower shingles.

B represents a plane field or plate oceupying the middle portion of the body A, and inclosed by a raised rib, b, having approximate ly the forni of a square, and arranged with its sides parallel with the corresponding sides of the body A.

O is a raised vertical rib extending from the lower corner of the rib b to the lip a, the latter being formed out of the lower portion of the rib C by cutting away the sides' of the latter 4 and of the adjoining portions of the body A.

D represents an upright raised rib extending from the upper corner of the rib b to the upper corner of the body A.

E E are raised ribs arranged on opposite sides of the central ribs, b, G, and D, and arranged parallel therewith-that is to say, the upper and lower portions of the ribs E are arranged `parallel with the ribs O and D, and the intermediate portions of thev ribs E are arranged parallel with the adjoining portions of the rib b. The body of the shingle is furthermore provided with outer raised ribs, F, arranged outside of the ribs E. The lower portions f of the ribs F are arranged vertically, while their upper portions f extend along the upper edges of the shingle. The bodyA of the shingle extends beyond the vertical portions f of the ribs F, forming ears or lips g, provided with nail-holes g.

7i are openings or perforations formed in the 'vertical portion f of the ribs F, near their lower ends, and adapted to receive the point a of the next higher shingle.

In laying these shingles on the roof, as represented in Fig. 2, the vertical portion f of the rib F rests on the vertical portion f of the rib F of the next adjoining shingle, and both rest on the vertical rib D of the shingle next below. The ear g of one shingle rests on the body A between the ribs F and E of the adjoining shingle. 'Ihe openings h n the two ribs ff, resting one upon the other, coincide, and the rib C of the next higher shingle rests on the ribs ff, andthe point a passes through the openings L in both ribs and engages under the lower rib, thereby firmly securing the lower end of each shingle in place. As the openings h are formed in the crowns, ridges, or raised portions of the ribs f, and do not extend down to the body of the shingle, water is prevented-from entering through the openings. The body A is provided at its upper end, on opposite sides of the rib D, with nail-holes i, and between the ribs f and E with nail-holes j, all of which are made somewhat larger than the nails, in order to permit the shingles to move slightly in expanding and contracting; The lower portions b of the rib b rest upon the marginal portions f of the ribs F of the two shingles next below, and the lower portions e of the ribs rest upon the upper portions c of the ribs E of the shingles next below, thereby forming tight joints between the several vshingles and unobstructed waterways. The side corners oi' the central square rib Z) are made blunt and parallel with the upright portions of the ribs E and F. The square rib I) stiffens the body vof the shingle considerably in all directions, and the ribs E and F, arranged parallel therewith, niaterially augment the rigidity of the shingle.

In constructing the shingle the body is first cut out, the holes '/L and nail-holes are then stamped through the same, and iinally the ribs are stamped into the body.

The center iield, B, niay be provided with a raised ornamental figure, K, it' desired.

fe claim as our inventionW l. A metallic shingle having its body A provided with a central plane portion, B, inclosed by a rib, b, and ribs C and D, extending downwardly and upwardly from the lower and upper corners of the rib b to the lower and upper corners of the body A, substantially as set forth.

2. A nietallio shingle having its body A provided with a central plane portion, B, inclosed by a rib, Z), ribs C and D, extending downwardly and upwardly from the lower and upper corners of the rib D tothe lower and upper corners oi' the body A, and upright ribs, EE and F F, arranged on opposite sides of the central rib, I), substantially as set forth.

3. A metallic shingle having its body provided with a central plane portion, B, inclosed by a rib, b, arib, D, extending upwardly from the upper corner ofthe rib b, a rib, C, extending downwardly from the lower corner of the t rib b, and provided with a lip, a, and outer ribs, F, having openings it, substantially as set i'orth.

et. A metallic shingle having its body provided with a central plane portion, B, inclosed by a rib, I), a rib', D, extending upwardly from the upper corner ofthe rib b, arib, C, extending downwardly from the lower corner of the rib b, and provided with a lip, a, outer ribs, F, having openings 71, and plane ears g, arranged outside of the ribs F, substantially as set forth.
